Subject[PATCH 46/75] bridge: fix switched interval for MLD Query types
Date
3.8.13.6 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: =?UTF-8?q?Linus=20L=C3=BCssing?= <linus.luessing@web.de>

[ Upstream commit 32de868cbc6bee010d2cee95b5071b25ecbec8c3 ]

General Queries (the one with the Multicast Address field
set to zero / '::') are supposed to have a Maximum Response Delay
of [Query Response Interval], while for Multicast-Address-Specific
Queries it is [Last Listener Query Interval] - not the other way
round. (see RFC2710, section 7.3+7.8)
